我已经遵循了创建项目的 firebase 的所有步骤。当我运行我的应用程序时，我收到以下错误：E/FirebaseInstanceId: Failed to get FIS auth token java.util.concurrent.ExecutionException: com.google.firebase.installations.FirebaseInstallationsException
我在 build.gradle 中添加了必要的库
但它仍然给我错误。是否有任何解决方案。
完整的堆栈跟踪如下：

当我触发查询以获取CursorAdapter的Cursor对象时,我得到:
IllegalArgumentException: column '_id' does not exist when call to CursorAdaptor
但我没有名为"_id"的columen.
谁能告诉我为什么会收到这个错误？

有人知道请让我知道..
我实现了一个包含活动组mainActivity的项目.此主要活动包含3个其他活动组.
当我尝试启动myaccountactivity这是一个活动组时,它适用于api超过1.6,但如果我试图在1.6上运行它我会得到以下的错误
